Chapter 4.2. Configuring components via components.xml reads "Sometimes we want to reuse the same components.xml file with minor changes during both deployment and testing. Seam lets you place wildcards of the form @wildcard@ in the components.xml file which can be replaced either by your Ant build script (at deployment time) or by providing a file named components.properties in the classpath (at development time). You'll see this approach used in the Seam examples." Isn't that supposed to be components.properties at deployment time vs. Ant at development time?
